Antonio Carlos Nascimento, 53, known as 'Kawex' sings during an activity called "radio" time in an area known as "cracolandia," or crackland, a dangerous wasteland of about eight blocks in the historic center of Sao Paulo, Brazil, February 11, 2021. During "radio" time, which is organized by Flavio Falcone and Andrea Macera, homeless people in crackland can request songs and even rap along as part of a project run by Falcone and Macera. "Sao Paulo at night, the world is divided in two. Another world that no one wants to see, a world where one cannot distinguish love from evil which comes to life when our city grows dark. Between world and underworld there is no luck and bad luck," said Nascimento. REUTERS/Amanda Perobelli SEARCH "CRACKLAND PEROBELLI" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES
